Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ranging telescopes, in particular to a composite reticle and a telescope. Background Art
[0002] A rangefinder telescope is an optical device that integrates a laser rangefinder function into a telescope platform. This allows users to measure the distance to a target while observing, providing useful information for activities such as shooting sports. Currently, there are two main methods for displaying numerical information such as distance on rangefinder telescopes. One method involves placing a transparent display screen, such as a TOLED or PLLC, at the focal plane of the telescope's objective lens, allowing direct viewing through the eyepiece. The other method uses a lens combined with a prism to project a display screen outside the main optical path onto the focal plane of the objective lens, with the image of the display screen observed through the eyepiece. The first method inevitably reduces the transmittance of the telescope's main optical path. Furthermore, because the PDLC does not emit light itself, the numerical value cannot be clearly seen in low light conditions. The second method also complicates the optical path, increasing the size of the telescope, the difficulty of assembly, and the cost. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a composite reticle and a telescope in view of the above deficiencies.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] Furthermore, the outer sides of the graticule, protective glass and self-luminous display screen are covered with a graticule seat.
[0009] Furthermore, the reticle and the protective glass are glued together using optical glue.
[0010] Furthermore, the self-luminous display screen is glued to the protective glass and / or the graticule plate using optical glue; or the self-luminous display screen, the protective glass and the graticule plate are fixed using a pressure ring.
[0011] Furthermore, the graticule is a circular plate;

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Example 1:
[0029] like Figure 1 As shown, a composite graticule includes a graticule 1, a protective glass 2, a self-luminous display screen 3 and a graticule base 4.
[0030] The reticle 1 is a circular plate, and reticle lines 12 (i.e., scale lines) are etched on a first surface 11 of the reticle 1;
[0031] A notch 21 is provided on the side of the protective glass 2, and the shape of the notch 21 is the same as that of the self-luminous display screen 3. When the self-luminous display screen 3 and the protective glass 2 are combined, a complete circular plate is formed.
[0032] The reticle seat 4 has a cylindrical mounting groove in the middle, and the reticle 1, protective glass 2 and self-luminous display screen 3 are installed in the mounting groove.
[0033] The self-luminous display screen 3 can be an OLED display screen or a LED display screen.
[0034] The grating plate 1 and the protective glass 2 are glued together with optical glue, and the self-luminous display screen 3 can be fixed in the notch 21 by a pressure ring. The self-luminous display screen 3 can also be glued to the protective glass 2 and / or the grating plate 1 with optical glue to combine the grating plate 1, the protective glass 2 and the self-luminous display screen 3.
[0035] The first surface 11 of the reticle 1 and the display surface of the self-luminous display screen 3 are in the same plane, that is, on the focal plane of the objective lens of the telescope 5. Therefore, the user can observe the display screen and the reticle at the same time. Figure 3 As shown;
[0036] Since the self-luminous display screen 3 emits light by itself during display, no external lighting is required, thus avoiding the need for an illumination light source to introduce stray light and affecting the transmittance of the graticule 1 , so that the display screen and the graticule lines can be clearly seen at the same time.
[0037] In order to further improve the transmittance of reticle 1, an antireflection film is coated on the second surface of reticle 1 and the side of protective glass 2 away from reticle 1 (i.e., the air-exposed surface of the composite reticle), thereby improving the transmittance of the entire composite reticle.
[0038] Example 2:
[0039] The second embodiment is a telescope with the composite reticle in the first embodiment.
[0040] like Figure 2 As shown, the composite graticule is arranged on the focal plane of the objective lens of the telescope 5.
[0041] When observing through the eyepiece, since the graticule 1 and the self-luminous display screen 3 are both located on the focal plane, the display surface of the self-luminous display screen 3 and the switching line 12 can be seen at the same time.
[0042] When in use, aim at the target through the reticle 12, trigger the distance measurement (the ranging telescope generally uses laser ranging, which is a common technical means in this field and will not be described in detail here), and the ranging result is displayed on the display surface of the self-luminous display screen 3, as shown in FIG. Figure 3 shown.
[0043] The above description is merely an example of the preferred embodiment of the present invention. Any details not described in detail are common knowledge within the art. The scope of protection of the present invention is determined by the claims. Any equivalent modifications based on the technical teachings of the present invention are also within the scope of protection of the present invention.
